Selvedge Uncurlers and Web Guiders
E+L KF 2020 Pneumatic Web Guider and Selvedge Holder
Pneumatic edge holder that keeps the web centred and the selvedge open at the stenter infeed.
Product Overview
The E+L KF 2020 is a pneumatic web guider and selvedge holder mounted at the infeed of a stenter frame, where it holds the fabric edge open and steady in the moment before the pins or clips take hold.
Air pressure does the gripping instead of a hard mechanical jaw, so the edge is held without being crushed. Yehang supplies the unit together with the wear parts that go around it, so a mill can order the guider and its replacement components from one line item.
Key Benefits
- Holds the selvedge open at the exact point where curled edges normally cause missed pins
- Air-actuated grip keeps light and elastic fabrics flat without pressing marks into the edge
- Mounts at the infeed of oil-free guide stenter frames alongside existing uncurler hardware
- Available with or without grease packing, so it suits both lubricated and oil-free chain lines
Who It Is For
- Dyeing and finishing mills that keep losing production time to edge faults at the stenter entry
- Maintenance teams replacing an aged web guiding unit on a Monforts, Bruckner or Artos frame
- Buyers sourcing E+L style infeed hardware together with the chain and pin parts behind it
Problems It Solves
- Curled selvedges arriving at the pin bed and being pinned folded, which shows as a defect down the whole roll
- Edge damage from rigid mechanical holders on jersey and spandex blends
- Having to buy the guider from one supplier and its wear parts from another
Application Scenarios
- Infeed of a stenter frame running knitted goods that curl as soon as tension drops
- Finishing lines where operators are hand-feeding edges into the pin bed at low speed
- Mills changing fabric type several times a shift and needing a guider that copes with both light and heavy qualities
Technical Features
- Pneumatic actuation, so holding force is set by air pressure rather than spring tension
- Supplied in a greased and a grease-free build for different guide rail conditions
- Metal body in a silver finish, sized to sit at the stenter infeed
- Unit weight approximately 0.6 kg

Certifications. We make no certification claim for this part. The original company statement is that products comply with international quality standards; no certificate is named and none is asserted here. Ask us directly if your procurement process requires documentation.
Comparison With Other Options
Against a fixed mechanical edge holder, the pneumatic version applies a set holding force instead of a fixed clamp gap, so it copes with a change of fabric weight without re-shimming. Against a contactless air spreader alone, it also holds position, which matters when the edge has to arrive at a specific point in the pin bed.
Use Guide
Mount at the infeed, upstream of the pinning point, on the existing bracket line
Connect to clean dry compressed air and set the lowest pressure that still holds the edge flat
Run a short length of the lightest fabric in the schedule and check the edge under the press wheel
Raise pressure in small steps if the edge lifts, not in one jump
Inspect the fabric contact faces weekly and wipe off finish build-up
FAQ
Questions About E+L KF 2020 Pneumatic Web Guider and Selvedge Holder
Which stenter frames does this fit?
It is supplied for oil-free guide stenter frames and is fitted to Monforts, Bruckner, Artos, IL SUNG and LK lines. Because infeed brackets differ between machine generations, send us a photo of your mounting point and we confirm the interface before you order.
Do I need grease on this unit?
Both builds are available. Lines that already run a greased guide normally take the greased version; oil-free guide lines take the grease-free one. Tell us which guide you run and we ship the matching build.
What air supply does it need?
Clean dry shop air. Start at the lowest pressure that keeps the edge flat and work up, because over-pressurising is what marks delicate fabric.
How long is delivery?
Stock items ship within 7 days of order confirmation. If your mounting interface needs matching we confirm the lead time with the drawing.
Can you supply the wear parts as well?
Yes. We make the pin plates, holders, chains, clips and PEEK parts that sit downstream of this unit, so the infeed station and the chain can be ordered together.
How is it packed for export?
Individually wrapped and boxed, then palletised or cartoned depending on order size. We can consolidate it with chain and pin plate orders in one shipment.

Guides That Cover This Part
What Is a Stenter Machine and How Does It Work
The stenter heat-sets and dries fabric by stretching it to width and holding it there under controlled heat.
Key Parts of a Stenter Machine
Entry section, clip or pin chains, rails, heating chambers, exhaust, blowers, temperature control, width adjustment and weft straightener.
Pin Stenter or Clip Stenter Which To Use
Clips leave no pin marks and suit thicker fabrics; pins hold more tension and run faster, to 100 m per minute.
Send A Sample And We Will Match The Profile
Seat profiles and geometry changed across frame generations, so the part itself is more reliable than a model number. We identify it and quote the matching specification.
